Water in abundance should be provided duringthe first season or two in order to keep the tree in active growth, butthe amount should be reduced in the late fall, as previously stated,to induce the tree to stop growth and mature its new wood in prepara-tion for winter. However, when very hot days occur in late summeror fall, water should always be given, if only a bucketful at a time toeach young tree. Avocados require about the same amount of irrigationwater as lemon trees. 388 UNIVERSITY OF CALIFORNIA EXPERIMENT STATION. o X> r** -< o rZ A •+-< o3 — o3 Sh C3 -G <u -»-» XI d «H • r* O t«?> 3 fa O 03 -4J 03 fa d d * u O • 1-103 bc-d -»-> 83 O o3 ,d i W. o3d 0 03 <o T3 ,g o3 -M -ij ^^ bfi 03 • i—i fa 03 T3 -u d S I—i ,0 -1-3 CC © £ q> rfi H <* bi Bulletin 254 THE AVoCADO IN CALIFORNIA 389 It is often desirable to top-work large seedlings or trees of onevariety to another. This has been successfully accomplished by bud-ding into new wood forced out for the purpose. The trees are cutback severely in the spring and the ends of the stubs are covered withheavy grafting wax or asphaltum paint to prevent decay. Only threeor four of the new shoots should be left, and when these have reacheda diameter of three-fourths of an inch they may be budded in thesame manner as seedlings. The shoots from the buds grow r
